Specification of Letters Patent.

y Patented July 7,1914.

Application filed May 5, 1913. Serial No.` 765,449.

To all whom t may concern Be it known that l, CHARLES CARREYN, a citizenof the United States of America, residing at Detroit,kin the county of"Wayne and State of Michigam have invented cer tain new and usefulImprovements in Flush-Tanks, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention relates to a flush tank and a disposition of the supplyand outlet valves therefor whereby the tank may be readily disconnectedand bodily removed from the supply and outlet pipes without dismountingany of the valve mechanism.

The invention consists in the matters hereinafter set forth and moreparticularly pointed out in the appended claim.

ln the drawings, Figure 1 is a view in vertical section of a tank andvalve mechanism therein that embody features of the invention; Fig. 2 isa plan View thereof.

As herein shown in preferred form, a tank 1 of suitable design andmaterial, is provided with an inlet valve casing 2 that is insertedthrough an opening in the base 3 of the tank and is secured thereinbetween an outer stop-collar A and an inner tting 5, gaskets 6 beingemployed to prevent leakage. The depending enlarged head 7 of the casinghas an inner annular valve seat 8. A suitable cap 9, that is fitted forconnection with the supply pipe, is screw-threaded on or otherwisesecured over the head 7, the cap having an inner shoulder that forms anannular valve seat.

A conical closure 10 that is adapted to seal `the opening through theannular seat 8 upwardly and through the cap 9 downwardly when detachedhas an upright stem 11 in sliding engagement with a guide openingthrough the fitting 5, the latter having side outlets 12 discharginginto the tank. Preferably, the stem is jointed, a coupling 30 affordingsuitable connection. The stem is also in sliding engagement with abracket 13 in the tank. A ioat 14C is adjustably secured as by a slidering 15 and set screw 16 on the stem 11. A dribble pipe 17 extends froman upper outlet in the fitting 5 to the upper portion of the tank andhas a downturned outlet end 1S.

A tubular outlet fitting 19 in an opening in the base of the tank inwhich'it is secured 'as by a stop-collar 2O and suitable gaskets 2l, hasan upper annular valve seat flange -22 thatl may be closed by aspherical float 28. They latter is in sliding engagement on a tubularstem 24 whose lower .end portion is adapted to loosely rest on theflange 22. The upper end portion of the stem passes through a guidebracket 25 on the tank. An operating lever 26 is pivoted on an arm 27 ofthe bracket 25 to extend thro-ugh a slot 28 in the tank wall, the innerend of the lever being articulated to the stem 24@ to raise the latterand the other arm acting on the upper end of the stem 11 to depress thelatter and force the closure 10 from seat. The outlet 18 of the dribblepipe 17 is arranged to discharge into the stem 24 whereby the desiredamount of water may be admitted into the receptacle to which the tank isconnected. A stop collar, bracket 29 or other means may be used to limitthe upward movement of the float 23 on the stem 24.

In operation downward movement of the outer end of the lever lifts thesealing float from the outlet and simultaneously opens the inlet valve.When the lever is released the intake valve remains open until such timeas the downward movementof the outlet lioat has closed the outlet valveand the level of the tank contents has reached the point where the floatthat controls the inlet valve has raised the closure of the latter toseat. The dribble pipe performs its usual function of supplying thedesired amount of water through the outlet stem for the receptacle towhich the tank is attached.

As a result of the connections and the arrangement of the valves in thebase of the tank, the outer couplings between the valves and the supplyand outlet pipes may be removed and the tank lifted bodily withoutdisturbing the adjustment of the inlet and outlet valves. Or if theupper section of the inlet closure stem is unscrewed the closure seatsitself on and seals the opening through the cap. As the valves aresimple in construction they are readily assembled in operative relationto their ycontrolling floats and lever and are not liable to be thrownout of adjustment or otherwise renl dered inoperative.

Obviously changes in the details of construction may be made withoutdeparting v ported fitting mounted upon the linner vendl from the spiritof my invention and' I do ynot care to limit myself to any particularform or arrangement of parts. .w V4

What I olaimisz-f i. y

The combination with a flushing tank, of a hOllOV casing having atubular stemeX"-- tending through the bottom of said tank-,a-

of the tubular stem of said casingfor de* tachably retaining the stem ofsaid casing" in engagement with said tank, said fittingv 4having lateraloppositely Vdisposed ports, 'a Vertical port andan angularlydisposedport adapted to accommodate a dribble pipe, said easinghavingv a'valve.seat in the outer end,

thereof and the outer` Walls of saidfcasing adapted to engage said Valveseat, said valve having a rodextending through said stem land guided bythe vertical port of said ty ting.
